    Hi Folks,

    I am a newbie and am learning to configure Frame Relay on my home lab.
    I would appreciate your time and effort if you could kindly guide me in
    the right direction. I have three routers (One 2521, and two 2503's). I
    shall refer to them as R1, R2 and R3 respectively. The final objective
    is to reach from R1 to R3. I am first testing connectivity between R1
    and R2. R1's DLCI to R2 seems to be deleted inspite of using
    frame-relay map

    R1 is configured as a frame relay dte device.
    R2 is configured as a frame relay dce device. frame-relay switching is
    turned ON at the global level.
    R3 is configured as a frame relay dte device.

    +------------+ +------------+
    +------------+
    | R1 |<------------>| R2 |<------------>| R3 |
    +-------------+ Cab 1 +------------+ Cab 2 +------------+

    The three routers are connected via DTE-DCE cables. (I am simulating a
    Frame Relay cloud).

    Cab 1 ==> The cable with the DTE end is on R1. The cable with the DCE
    end is on R2
    Cab 2 ==> The cable with the DTE end is on R3. The cable with the DCE
    end is on R2.

    R1 serial interface has an ip of 10.0.0.1 / 8
    R2 serial interface has an ip of 10.0.0.2 / 8

    My interfaces on R1 and R2 are up. I am trying to ping from R1 to R2.
    LMI exchanges look good.

    It is an attribute of serial interfaces, on Cisco devices at least, that
    you can't ping the local interface if the link itself isn't working, i.e.
    the "ping" has to travel to the far end of the link and be returned to you.

    Also, on frame relay interfaces you need a frame relay map for the local
    address, or you will get encapsulation failures when you try to ping it,
    i.e.

    ! On R1
    interface Serial1
    frame-relay map ip 10.0.0.1 102
    !

    You also appear to have mismatched DLCIa at the two routers.

    2521_R1#show frame-relay map
    Serial1 (up): ip 10.0.0.2 dlci 102(0x66,0x1860), static,
    CISCO, status defined, active

    R2_2503#show frame-relay map
    Serial0 (up): ip 10.0.0.1 dlci 103(0x67,0x1870), static,
    CISCO, status defined, active

    It's also a good idea to include the actual router configurations along
    with appropriate debugs etc. so anyone who might be inclined to reply
    doesn't have to reconstruct it first. That, and learning to trim
    responses, and not to top post.

    Hi Martin,

    First of all I would like to thank you for taking time out of your
    schedule and helping me out with my configs.

    I shall revisit my router configs per your recommendations and post my
    thoughts on the issue.

    Hi Martin,
    I realized my mistake at configuring the routers and corrected the
    same. I finally have my DLCI's active. However, I am now able to ping
    end-to-end as well as locally.

    Thanks a bunch for your help and guidance ... hope I can be of some
    help...

    Rgds,
